Spheres of light float in the space、they move on their own, shining brightly, then disappearing&mdash;as if they are softly breathing. When the spheres of light are touched by a person or receive an impact, the color of their light changes, and they emit a musical tone unique to their new color. They then resonate that color and tone to the spheres around them, changing to the same color and emitting the same tone, resulting in a chain reaction.
